Screening tools
All five take the value to screen plus an optionallists argument — a comma-separated set of source list slugs to narrow the scope (unknown slugs error). Responses match the REST /screen/* envelope: sanctioned is true only for government sanctions hits, flagged covers crime-intelligence and risk-exposure hits too, and matches names the list behind each hit.

Errors
Over-quota calls return a tool error (or, with x402 enabled, a payment challenge as the error result’s structured content). Invalid arguments — an unknownlists slug, a malformed IP — also come back as tool errors rather than protocol failures, so agents can read the message and retry.
